Abstract: PURPOSE:To contrive the reduction of mechanical correlation of a fuel element bundle, a wrapper tube and the like by applying the difference of working temperatures of coating tubes and the wrapper tube to use materials different in temperature dependency of swelling respectively. CONSTITUTION:A fuel assembly is formed so that many coating tubes 2 composed of the materials (cold working AISI 316 SS-Ti) in which titanium is added to cold working material 316 SS which is filled with fuel pellets 5 composed of mixing oxide of uranium and plutonium are bundled and covered by a wrapper tube 1 of a cold working material AISI 316. Thereby, since there is a peak of swelling at about 450 deg.C in the cold working material 316 SS-Ti and the swelling is suddenly lessened at the temperature equal to or more than said temperature, the maximum value of the swelling of the coating tubes is about 1/2, as compared with the case where the cold working material AISI 316 is used for both the coating tubes and the wrapper tube and the maximum value of the swelling of the wrapper tube is about 1/2, as compared with the case where the cold working material 316 SS-Ti is used for both the coating tubes and the wrapper tube.

Title: Transmission signal processing system
Inventor: MURATA HIROSHI
IPC: H04N1/409
Filed: 1980-09-10
Abstract: PURPOSE:To prevent the transmission of dirt of read-in section area of a transmission original, by fixing or rejecting the video information other than originals to white color. CONSTITUTION:A reflecting optical image 5 from an original incident via an optical system 3 is converted into a video signal 7 at a photo electric conversion circuit 4. The video signal 7 converted is given to a signal processing circuit 8, this is binarized, and black signals present at the region other than the original are fixed to white signals in the binary signal with a control signal 15 and outputted as to transmission video signal 16. The control signal 15 gives the output of an original detector 9 to an original width forming circuit 12 and it is obtained by applying the output to a video signal control circuit 14. Thus, since no video signal other than that on the original is transmitted, no dirt on the original can be printed on the reception paper.

Title: Still picture recording device and picture element data interpolating method
Inventor: OKAYAMA YUKO
IPC: H04N5/92
Filed: 1999-05-07
Abstract: PROBLEM TO BE SOLVED: To generate/record the still picture of high picture quality by calculating a difference between luminance signals in whole pixels of two field data which hourly continue, judging the pixels from a histogram showing the distribution of whole difference values, executing inter-field interpolation in the case of the moving pixel and executing intra-field interpolation in the case of the still pixel. SOLUTION: When it is assumed that pixel data are interpolated against an i-field, the difference of luminance signals between pixels in relative positions between fields is calculated against the whole pixels constituting an (i-1) field and an (i+1) field. Then, a histogram showing the distribution of the whole calculated difference values is generated. The minimum value and the maximum value of the difference value containing the prescribed rate of the whole difference values are obtained. When the pixels where the difference of the luminance signals among the pixels is within the range of the minimum value to the maximum value, the pixels are judged to be still. When they are not within the range, the pixels are judged to be moving.
